Overview

This document provides information about the Hyper-V role in Microsoft Windows Server 2008 R2 for Dell PowerEdge systems. Unless stated otherwise, the information in this document applies to all service packs of the operating system.

Windows Server 2008 R2 with Hyper-V is an operating system that includes a hypervisor-based virtualization solution.

Windows Server 2008 R2 With Hyper-V Features

The key enhancements of Windows Server 2008 R2 with Hyper-V as compared to Windows Server 2008 Hyper-V are:

Live migration

Dynamic virtual machine storage

Enhanced processor support

Enhanced networking support

From Windows Server 2008 R2 SP1 onwards, there are two additional enhancements:

Dynamic Memory—Allows the memory on a host machine to be pooled and dynamically distributed to virtual machines as necessary. Based on current workloads on a virtual machine, memory is dynamically added or removed. Dynamic memory allocation is done without service interruption.

RemoteFX—Introduces a new set of remote user experience capabilities that enable a media-rich user environment for virtual desktops, session-based desktops, and remote applications. RemoteFX enables a rich desktop experience for virtual machine users through a 3D adapter and USB redirection. The 3D scenarios in virtual desktops provide a virtualized graphics processing unit (GPU) within the virtual machine. RemoteFX provides intelligent capture and compression that adapts for the best user experience in both virtual and session-based desktops.

1 The PowerEdge 6800 and PowerEdge 6850 systems with Intel processors, identified by processor ID F48, support Hyper-V. To view the processor ID information, press <F2> during boot to access the system BIOS and then navigate to CPU Information.

NOTE: Download the latest BIOS version from support.dell.com.

NOTE: All PowerEdge 11th-generation systems and later support Hyper-V.

Enabling Hardware Features to Support Hyper-V

The following processor features are required to configure Hyper-V:

Extended Memory 64 Technology (EM64T)

Data Execution Prevention (DEP)

NOTE: By default, DEP is enabled in the BIOS of all Dell systems.

Hardware-assisted virtualization (Intel-VT or AMD-V)

NOTE: By default, hardware-assisted virtualization is enabled on the PowerEdge T105 system.

To enable hardware-assisted virtualization on Dell systems:

1Press <F2> at the POST screen to go to the BIOS setup.

2Navigate to the CPU Information section.

3Press <Enter> and navigate to Virtualization Technology.

4Select Enabled by toggling the left and right arrow keys.

5Save the selection and exit the BIOS setup.

Known Issues and Resolutions

NOTE: This section contains the issues that are specific to Hyper-V. For issues specific to Windows Server 2008 R2, see the Microsoft Windows Server 2008 R2 for Dell PowerEdge Systems Important Information Guide at dell.com/ostechsheets.

Virtual Machine (VM) Connection May Be Lost When Connected to a SCSI Hard Drive

Description In Hyper-V, a VM can either use an IDE or SCSI hard drive to connect to a virtual disk.

If you connect a Windows Server 2003 VM with a SCSI adapter to a disk located on an iSCSI target, you may experience connectivity issues with the VM. The issue occurs if you connect through the Pass through Disk option and the network connection to the target is subsequently lost.

The internal connection between the VM and the SCSI disk is not restored even after you reconnect the target. If you try to restore the connection by opening the disk management console, an error message is displayed, prompting you to initialize the disk.

Solution To workaround this issue, restart the VM.

Unable to Create Hyper-V VMs

Description Hardware-assisted virtualization is a pre-requisite for installing Hyper-V. The Hyper-V Role Configuration wizard allows you to install the Hyper-V role even if the Hardware Assisted Virtualization (Intel-VT or AMD-V) capability is disabled in the system BIOS. When you attempt to create or start a virtual machine, you may receive the following error message:

Virtual machine failed to initialize.

Solution To resolve this issue, enable the Virtualization Technology feature in the BIOS and reboot the system. The Hyper-V hypervisor loads successfully.

Important Information

Guest Operating Systems Installed Using the Dell Recovery Media Prompts for Activation

Description NOTE: The activation process described in this section applies only to guest operating system installations performed with the Dell recovery media.

You must enter a virtual PID key when you install a guest operating system in a virtualized environment.

Solution To activate the Windows Server 2008 R2 guest operating system using the Dell recovery media:

1 Boot into the guest operating system and choose the option to enter a new product key.

2 Enter the virtual key available on the right side of the Certificate of Authenticity (COA) sticker on your system.

The virtual key is different from the product key which is also present on the COA sticker.

3 Activate the Windows Server 2008 R2 guest operating system using the regular Microsoft activation channels—manually with the telephone or automatically through the Internet (if your virtual machine has direct access to the Internet).

For more information on Windows Server 2008 R2 activation, see microsoft.com/windowsserver2008.

Preventing Loss of VM Configurations While Upgrading Windows Server 2008 R2 Edition

Description

CAUTION: Upgrading Windows Server 2008 R2 editions

 

may cause loss of the virtual machine configurations for

 

the existing Hyper-V virtual machines.

 

Upgrading the host operating system in a parent partition

 

from one Windows Server 2008 R2 edition to another is

 

supported by Dell.

Solution

To prevent the loss of the virtual machine configuration, use

 

the Export/Import functionality in the Hyper-V Manager to

 

export the existing virtual machines prior to the upgrade.

 

After the upgrade is complete, import the virtual machines

 

along with the configurations.

Hyper-V Guest Operating System Installation Through DRAC/iDRAC May Fail

Description

If you are installing either Windows Vista, Windows Server

 

2008, or Windows Server 2008 R2 guest operating system on a

 

system running Hyper-V with an operating system ISO image

 

remotely attached to the Dell Remote Access Controller

 

(DRAC) 4 or DRAC 5 virtual media, the installation may fail

 

displaying the following message:

 

A required CD/DVD drive device driver is

 

missing. If you have a driver floppy disk,

 

CD, DVD, or USB flash drive, please insert

 

it now.

Solution

To resolve this issue, download the firmware version 1.61 for

 

DRAC 4 and 1.4.0 or later for DRAC 5 from support.dell.com.

 

 

Remote Network Connection May be Lost When Creating a Hyper-V Virtual Network

Description When you bind an external virtual network to a physical network adapter, the remote network connections may be lost temporarily during the virtual network creation process. The issue occurs if the remote network connection to the Hyper-V host uses the physical network adapter to which the new virtual network is bound.

Solution This feature is working as designed. In most cases, the remote connection is automatically re-established. To resolve this issue, it is recommended that you dedicate a specific network adapter in the parent partition strictly for managing the system. You must not bind the management network adapter to any Hyper-V virtual network. Also, you must make remote connections, if any, to the parent partition through the IP address of this management adapter.

10

Important Information

Hyper-V Virtual Machine Does Not Support TOE

Description Windows Server 2008 R2 is expected to support the ability to utilize the TCP Offload Engine (TOE) on child partitions for supported guest operating systems. This feature is still undergoing testing and must be enabled with caution.

Solution This is a known issue and will be fixed in a future Microsoft release. To workaround this issue, note down the IP address and enable remote desktop of the system before enabling the Remote-FX 3D feature. When the console is disconnected, use the IP address of the system to reconnect through the remote desktop option from a client.

DRAC Virtual Console is Disconnected if RemoteFX 3D is Enabled

Description When you connect to a system using the Dell DRAC virtual console from a client and try to enable the 3D option in Remote-FX feature with Windows Server 2008 R2 SP1, the console gets disconnected.

Solution This is a known issue and will be fixed in a future Microsoft release. To workaround this issue, note down the IP address and enable remote desktop of the system before enabling the Remote-FX 3D feature. When the console is disconnected, use the IP address of the system to reconnect through the remote desktop option from a client.
